Section 9VAC5-160-150 - Reevaluation of conformity

A. Once a conformity determination is completed by a federal agency, that determination is not required to be reevaluated if the agency has maintained a continuous program to implement the action, the determination has not lapsed as specified in subsection B of this section, or any modification to the action does not result in an increase in emissions above the levels specified in 9VAC5-160-30 B. If a conformity determination is not required for the action at the time NEPA analysis is completed, the date of the finding of no significant impact for an environmental assessment, a record of decision for an environmental impact statement, or a categorical exclusion determination may be used as a substitute date for the conformity determination date.

B. The conformity status of a federal action automatically lapses five years from the date a final conformity determination is reported under 9VAC5-160-130, unless the federal action has been completed or a continuous program to implement the federal action has commenced.

C. Ongoing federal activities at a given site showing continuous progress are not new actions and do not require periodic redeterminations so long as such activities are within the scope of the final conformity determination reported under 9VAC5-160-130.

D. If the federal agency originally determined through the applicability analysis that a conformity determination was not necessary because the emissions for the action were below the limits in 9VAC5-160-30 B and changes to the action would result in the total emissions from the action being above the limits in 9VAC5-160-30 B, then the federal agency shall make a conformity determination.
